Chesterton 186HT Bellows Cartridge Single Seal

Designed for high temperature services related to petrochemical and chemical plant processes
This high temperature version of the 186 seal is built with AM 350 bellows material as standard, and 718 InconelĀ® offered as optional.
Graphite secondary seals take the place of O-rings for high temperature services. The high strength, low spring rate bellows core delivers low heat generation and reliable sealing performance. A self-cleaning rotary bellows design will reduce the clogging ssociated with sealing fluids and solids in suspension.
